ELECTRIC SHOCK HAZARD. Disconnect all power before installing thermostat kit. Failure to do so could result in personal injury or property damage. Thermostat kit must be installed by a qualified person in accordance with the National Electrical Code, NFPA 70. INSTALLATION Step 1 1. Verify that the thermostat kit is compatible with your heater. HVH-TK-6 is a DPST line voltage thermostat, it can be used on 1O, 240V max. up to 25A and 1O, 277V up to 22A heaters. HVH-TK-5 is a SPST is a thermostat used in conjunction with a contactor. 2. Peel off “Chromalox” label located on the bottom front corner of the heater. Removal of the label will reveal the holes for mounting the thermostat (See Figure 1). 3.

Connect incoming power wiring to the black leads with wire nuts provided by others. See figure 4 for line voltage thermostat. See figure 8 for control voltage thermostat. For TK-5 thermostat kits with an internally provided control circuit, remove white jumper wire on terminal block between poles “C1” and “C2”. Connect blue wire of thermostat to pole “C1” and black wire to “C2”. See figures 5, 6 or 7. Figure 2 For TK-5 thermostat kits with an externally provided control circuit, remove white jumper wire on terminal block between poles “C2” and “C3”. Connect blue wire of thermostat to pole “C2” and black wire to “C3”. See figure 7. 2. Inspect wiring to make sure it matches the appropriate wiring diagram. 3. Close heater cover and reattach screws.
